Core tasks in translation & localisation

GLM (Z.ai) raises a concrete GDPR concern. Parent company Zhipu (Beijing) is subject to Chinese data and security legislation, regardless of where the servers are located. For sensitive data, self-hosting the MIT-licensed weights is the recommended mitigation. Weigh this heavily before deploying it in translation & localisation.

Confidentiality and GDPR

GDPR: Caution

Client source documents often contain personal data or trade secrets: never use the free consumer version of a translation tool for client material. Require a data processing agreement, check that your texts are deleted after translation and not used for training, and choose EU hosting where possible. Many translation contracts and NDAs with end clients prohibit passing texts to third parties without consent, so document which MT engine you use. And stay responsible for the content: AI translations read fluently but can reverse figures, negations and legal nuances.

The international service Z.ai runs through JINGSHENG HENGXING TECHNOLOGY PTE. LTD. (Singapore); personal data is in principle processed in Singapore. According to the data processing agreement, API content is processed in real time and not stored. GLM-5.2 is open-weight under MIT and can therefore be fully self-hosted or hosted through an EU provider.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
